The Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 versions utilize the Alert (ALR) module for managing and automating business notifications. The ALR tables and views form the backbone of this functionality, storing alert definitions, conditions, actions, and execution logs. DeepseekETRM (Enterprise Technical Reference Manual) provides comprehensive documentation on these database objects, enabling administrators and developers to understand, customize, and troubleshoot the Alert module effectively.

Core ALR Tables

The ALR architecture relies on several key tables:
  • ALR_ALERTS: Stores metadata for alert definitions, including names, descriptions, and statuses (enabled/disabled).
  • ALR_ALERT_CHECKS: Contains the SQL queries that define the conditions triggering alerts.
  • ALR_ALERT_OUTPUTS: Defines output variables used in alert messages and actions.
  • ALR_ALERT_ACTIONS: Specifies actions (email, concurrent program, etc.) executed when alerts trigger.
  • ALR_ACTION_SETS: Groups related actions for sequential execution.
  • ALR_ALERT_HISTORY: Logs alert execution details, including timestamps and outcomes.

Key ALR Views

Oracle provides views to simplify access to alert data:
  • ALR_V_ALERTS: Combines data from ALR_ALERTS with related tables for a comprehensive alert overview.
  • ALR_V_ALERT_CHECKS: Presents alert conditions with decoded SQL and frequency settings.
  • ALR_V_ALERT_ACTIONS: Displays action details with resolved recipient information.
  • ALR_V_ALERT_HISTORY: Offers filtered access to execution logs with status indicators.

Technical Implementation

The Alert module operates through a scheduled concurrent program (Alert Manager) that periodically checks ALR_ALERT_CHECKS for active alerts. When conditions are met:
  1. The system retrieves action definitions from ALR_ALERT_ACTIONS
  2. Executes specified actions (email, program, etc.)
  3. Records results in ALR_ALERT_HISTORY

Customization Points

DeepseekETRM documentation enables these advanced implementations:
  • Extending ALR_ALERT_OUTPUTS to include custom variables
  • Creating database triggers on ALR tables for additional processing
  • Developing custom reports using ALR views
  • Integrating with workflow through ALR_ACTION_SETS

Version Considerations

While core ALR structures remain consistent between 12.1.1 and 12.2.2, notable differences include:
  • 12.2.2 introduces enhanced security in ALR_ALERT_ACTIONS for OAuth integrations
  • The 12.2.2 ALR_V_ALERTS view includes additional columns for cloud readiness
  • Partitioning options for ALR_ALERT_HISTORY differ between versions

Performance Considerations

For optimal alert performance:
  • Index ALR_ALERT_CHECKS on FREQUENCY and LAST_CHECK_DATE
  • Purge ALR_ALERT_HISTORY regularly via concurrent program
  • Monitor long-running checks through ALR_V_ALERT_HISTORY
  • Consider materialized views for complex alert conditions
The DeepseekETRM documentation provides complete data dictionaries, including column-level details, constraints, and relationships between these objects. This enables precise customization while maintaining system integrity. Proper utilization of ALR tables and views allows organizations to implement sophisticated notification systems that proactively monitor business conditions across Oracle EBS implementations.
